Rapper Pharrell Williams put "X-Factor" in the most bizarre nutshell of all time ... claiming the show is just like "a girl with three t*ts."
Pharrell joins "X-Factor" as a guest judge this Sunday -- and while taping one of the segments, he told producers, X is "like a trifecta. It’s like you’re getting rock, you’re getting alternative mentality, you’re getting hip-hop influence, you’re getting the visuals."
Pharrell added, "Just being one thing is boring, right? You know, a girl with three t*ts ... that’s where it’s at!"
If you're not convinced, here's the 3-breasted woman from "Total Recall." We rest our case.
